.DISCUSSION...

Today through Tonight:

Latest satellite imagery showed a broad upper trough axis over
the Central CONUS. Over the ArkLaMiss a weak disturbance has
produced some isolated light showers this morning, which are
tracking to the northeast. On the surface a frontal boundary was
observed across my southeast counties. So for today Cam guidance
shows some convection across the south,which will decrease from
the north by this evening as the front exits the region for today.
Expect the activity to dissipate by late evening as drier air
pushes across the south from the north. Highs today will be in the
middle 80s. The drier air will bring in some cooler lows with
readings in the lower to middle 60s. /17/

Monday through Saturday:

Not too many changes have been made to the forecast for the rest
of this week. There is still good agreement among model guidance
that the western CONUS ridge/eastern CONUS trough pattern will
break down by midweek, allowing for generally zonal flow aloft to
set up after that. A few quick moving shortwave troughs will pass
well to our north through the course of the week. At the surface,
high pressure will dominate much of the country for the next few
days as a 1025 mb surface slides eastward and weakens. Drier air
and a northeasterly component to the low-level flow around the
surface high will keep rain chances minimal across the ArkLaMiss
region for Monday and Tuesday. Then by Wednesday a return of
southeast winds will bring an increase in moisture and an uptick
in typical summertime diurnal convection. Although a broad ridge
will set up over the South by late in the week, afternoon shower
and thunderstorm activity will likely keep high temperatures in
check near seasonal norms. /NF/
